Despite around-the-clock repairs, officials say that restoring Calgary’s water service will take longer than expected — and time is running out.

Repairs were paused this week after two workers were injured at the site. Meanwhile, Mayor Jyoti Gondek told reporters that water consumption has increased, bringing it over the “safe threshold.”

“Our supply is lower than it has been in the last few days,” she said. “There’s still a real chance we could run out of water. I know this is inconvenient, I know it’s hard to hear that we must do more. But we simply must.”
